我有以下示例配置使用带有Webpack 4的mini-css-extract-plugin:

entry: {
   a: ['./js/a.js', './scss/a.scss'],
   b: ['./js/b.js', './scss/b.scss']
},
module: {
    rules: [
       [...],
       {
        test: /\.(css|sass|scss)$/,
        use: [
            MiniCssExtractPlugin.loader,
            {
                loader: 'css-loader',
                options: {
                    importLoaders: 2,
                    sourceMap: true
                }
            },
            {
                loader: 'postcss-loader',
                options: {
                    plugins: () => [
                        require('autoprefixer')
                    ],
                    sourceMap: true
                }
            },
            {
                loader: 'sass-loader',
                options: {
                    sourceMap: true
                }
            }
        ]
},
optimization: {
    splitChunks: {
        cacheGroups: {
            js: {
                test: /\.js$/,
                name: "commons",
                chunks: "all",
                minChunks: 7,
            },
            css: {
                test: /\.(css|sass|scss)$/, …

我有一个在 C# 中使用实体框架的简单场景。我有一个实体帖子：

public class Post
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
}

在我的 PostManager 我有这些方法：

public int AddPost(string name, string description)
    {
        var post = new Post() { Name = name, Description = description };

        using (var db = new DbContext())
        {

          res.Validate();
          db.SaveChanges();
          return res.Id;
        }
    }

    public void UpdatePost(int postId, string newName, string newDescription)
    {
        using (var …
